Various stage theories of disease progression have been developed. However, in clinical practice, professionals speak roughly of three stages. One exception - hoodia diet weight loss pills. In mild stage dementia, the newly diagnosed patient has significant cognitive losses resulting in disorientation and dysfunction, and often displays affective flatness and possibly depression. In moderate stage dementia, the patient forgets that he or she forgets, thereby gaining relief from insight into losses. Some patients will at this point adjust well emotionally to a life lived largely in the pure present, although some long-term memories are still in place. The recognition of loved ones is usually still possible. However, as many as one-third of patients in the moderate stage will struggle with emotional and behavior problems, including agitation, combativeness, paranoia, hallucinations, wandering, and depression. A small percentage becomes sexually disinhibited. The advanced stage of dementia includes a loss of all or nearly all ability to communicate by speech, inability to recognize loved ones in most cases, loss of ambulation without assistance, incontinence of bowel and/or bladder, and some weight loss due to swallowing difficulties. The advanced stage is generally considered terminal, with death occurring on average within two years. AD, however, is heterogeneous in its manifestations, and defies simplistic staging. For example, while most people with advanced AD will have no obvious ability to recognize loved ones, this is not always the case.
